摘　　要：以六羰基钨[W(CO)6]为催化剂,合成了聚吲哚芴(P1)、聚梯型四苯(P2)、聚梯型五苯(P3)和小分子9-联吲哚芴烯(S1).该类聚合物的重复单元含有联芴烯结构,通过芴9位的双键连接.光学和电化学等实验结果表明,聚合物无荧光发射,是一类窄带隙的共轭聚合物,其中聚合物P1薄膜的紫外吸收值最大波长为710 nm.A series of novel conjugated polymers containing bifluorenylidenes units was synthesized under mild conditions with W（CO） 6 as the catalyst, and the repeated units of the polymers were linked at 9 position of fluorine by the double bond. The new polymers represent narrow band gap, and the maxium absorption of polymer P1 in film is peaked at 710 nm. In most cases, the conjugated polymers containing fluorenes units show strong photoluminescence（ PL） emission, while the synthesized polymers show no photoluminescence （PL） emission. The synthesized polymers contain new backbone structure. Their optical and electrochemical properties were studied in detail.
